RE: Roof Joist Anchorage

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Rather than trying to use the joist as a wall anchor, you could use 4x
blocking between the trusses bolted to an angle which is anchored to a bolt
cast in the block wall and threads extended vertically.  You would need to
block and strap out far enough into the diaphragm to develop the capacity
you need.

Subject: Roof Joist Anchorage

I am working on a project where we have open web wood joists (such as the
Trus Joist TJS ) sitting on top of a masonry wall.  Does anyone know of a
way to tie the joists to the wall?  The Simpson PA series requires that one
end be embedded in the masonry.  With the type of joist we want to use, this
is not possible (top chord bearing with chord sitting on top of a 2x or 3x
sill plate).  The local sales rep does not have any ideas.  We are in Zone 3
so really need to tie the joist to the walls.  Any ideas?
